Wine May Help Type 2 Diabetics With Cholesterol and Heart Health

A recent study suggests that a nightly glass of red wine may help people with type 2 diabetes manage their cholesterol and cardiac health. The researchers also found that both red and white wine may help certain diabetics with sugar control.


Participants in the study included 224 patients with controlled diabetes between the ages of 45 and 75 who generally did not drink alcohol. The participants were given either 150 mL of mineral water, white wine, or red wine with dinner. Over the course of the two year study, their alcohol consumption was gradually increased, in conjunction with a healthy, Mediterranean diet without caloric restriction.


The researchers found that red wine consumption performed best at improving overall metabolic profiles by increasing HDL cholesterol and apolipoprotien A1, which is one of the major parts of HDL cholesterol. It was also associated with a decrease in the ratio between total cholesterol and HDL cholesterol.


Additionally, they found that people who were slow-alcohol metabolizers saw an improvement in blood sugar controls, while fast-alcohol metabolizers did not. Slow-alcohol metabolizers clear blood alcohol more slowly, whereas fast-alcohol metabolizers clear it more rapidly. The researchers found that one in five of the study participants were fast-alcohol metabolizers, as determined by ADH enzyme genetic variant tests.


Neither red nor white wine affected the participant’s blood pressure, liver function tests, adiposity, or adverse events or symptoms. However, the researchers did note improved sleep quality in both wine groups.


Researchers from Ben-Gurion University of the Negev and Soroka Medical Center in Israel conducted the study. It was published on October 20, 2015, in the Annals of Internal Medicine.


Red wine polyphenols have powerful antioxidant properties and have been associated with numerous health benefits. These include improving heart health, reducing the risk of Alzheimer’s, reducing cholesterol and inflammation and destroying free radicals.


It’s important to drink moderately, as high consumption of alcohol can reverse any health benefits received. A high quality supplement is a good alternative if you do not wish to consume red wine.
